Pyramid will market the 256-acre site, leveraging Cushman and Wakefield's international reach, to find new tenants for the 2.5 million-square-feet of existing space.

Perfit said property owner Alan Ginsberg chose to remarket now to take advantage of TechCity's inclusion in Start-Up NY, a tax-break program announced last year by Gov. Andrew Cuomo.

TechCity, located about a mile from SUNY Ulster's Business Resource Center on Albany Avenue, is considered an extension of the tax-free zone centered around the community college.

Start-up companies and businesses moving to New York from out-of-state can participate in Start-Up NY and operate tax-free for 10 years.

The incentives apply to only 200,000 square feet at TechCity, but Perfit plans to request a waiver to increase the space that can offer the benefits.

Ginsberg moved the listing to a new broker in part because he recently lost a major tenant, Hunter Panels, Perfit said. Hunter Panels, a roofing materials manufacturer, built a 360,000-square-foot plant in Orange County.

Some of TechCity's current tenants include Bank of America and Farm to Table Co-Packers.

Perfit plans to target sectors like high-tech office, education and manufacturing in his marketing campaign for the property. The site features a rail spur.

TechCity is already competing with another site for a manufacturing prospect, Perfit said. The prospect, which Perfit did not name, looked at 57 acres of land at TechCity near the New York State Thruway.

Perfit, who is also the treasurer of the Ulster County Industrial Development Agency, said during Wednesday's IDA meeting that TechCity may apply for the county's Ready2Go program, a fund that helps projects advance through the planning process.

Contamination left at the site by IBM has challenged redevelopment at TechCity. Plans are in the works to clean up the toxins, left over from computer motherboard manufacturing.
